I’ve had this thought running through my head.
When I read the Armor of God in Ephesians 6, as an evangelist, I really want the Shoes of the Gospel of the Peace to represent going out and sharing the gospel. But every single commentary I read says that is not the case. All the weapons are defensive expect the sword- which is the Word of God. The sword is both offensive and defensive.
As I was contemplating this, I realized that is because the gospel message is meant to be shared as obviously stated by the Great Commission. (Matthew 28:16-20) But here Paul is speaking of using the gospel as a defense, so you can stand strong against schemes of the enemy. Apologetics.
The Shoes of the Gospel of Peace represent Apologetics. Knowing the gospel brings you peace during an attack and gives you the stability needed to withstand. But the Word of God, your sword, is your offence to the counter the attack.
In short- how awesome is our God! We have all we need to not only defend the faith but share it as well!
